So here are some waveforms when the ardruino is loaded with first program:
When program is not running (top waveform is filtered through 4k7 and 10n RC network)
And there is picture when is running:
Your idea for LCD screen is great, it would be nice to have basic parameters displayed on screen, i think amps, volts, and hertz is more than enough, so you can use 16×2 LCD where top row could display these parameters, and botom row could display system informations such as inverter running and fault codes.
Which protocol are you planning to use for display ? I2C or SPI ?
Im looking forward to see program version with OCP and maybe OTP.
@gaspo here i tried to reproduce your waveforms and with edge triggering i didnt manage to get stable waveform, duty cycle was all over the place, and then i use pulse triggering and manage to get stable waveform
I left my trigger menu opened so you can see what settings i used
